2 Claims.

The present invention relates to bats made of inorganic wool or the like adapted for insulating purposes and more particularly has reference to markings applied to the bats in a manner and for the purposes hereinafter fully set forth.

In the use" of wool bats, particularly those of glass wool and the like, it is customary to stack square sheets of the flufiy material on top of one another and pack them into containers or cartons. When glass wool bats are placed on top of one another, the dividing line between them becomes almost indistinguishable and it is possible, when unpacking the same to split the bat and create new dividing lines, either deliberately or inadvertently. When a contractor, for example, is insulating a floor or the like, he may split the bats or stretch them in a manner to cover a given area with a less number of bats than is required if they are properly placed. The art was faced with these and other problems which this invention succeeds in solving.

It is an object of the present invention to provide a bat which may be stacked and packed without rendering the dividing lines imperceptible.

Another object of the invention is to provide -a glass wool bat which cannot be split or stretched without detection.

It is a further object to provide an apparatus and a method of applying a marking to a continuous belt of glass wool in a simple and inexpensive manner before it is cut into individual bats.

Other objects and advantages of the present invention will become apparent from the following description taken in conjunction with the following drawing, in which Fig. l is a fragmentary perspective view of a continuous belt of glass wool and my apparatus for applying markings thereon; and

Fig. 2 illustrates a perspective view of a partly opened package of glass wool bats.

Referring to the drawing with more particularity, reference character I represents a continuous belt of glass wool or the like as it is conveyed along a conveyor belt 2 from the usual forming machine (not shown). The rollers 3 permit the continuous belt to travel in the usual manner. Mounted .over the glass wool belt I are spray guns 4 which are adapted to eject a coloring substance to form colored stripes 5 onto the top of the moving belt. Interconnectecl'with the guns are mixing chambers 6 into which is introduced a paint or ink through the conduit 1, and a compressed gas such as air or steam through the conduit 8. The ends of the conduits of course are connected to sources of materials and may be mounted in any suitable manner as those skilled in the art will readily 5 understand.

The spray guns when in operative position, are mounted relatively stationary to the advancing glass wool belt so that there may be applied to the top of the belt, a continuous and 10 uniform colored stripe 5. It has been found advantageous to provide a color or paint which penetrates the wool for a short distance, so that, as the advancing glass wool belt is chopped into bats of suitable size and placed one upon 1 the other as shown in Fig. 2, the'ends 9 of the colored stripe are visible.

When the carton l0 into which the bats are packed, is opened and the bats are ready for installation, the dividing lines H between the bats, become readily apparent. In this manner, the bats will not be split when unpacking and if a workman or contractor deliberately splits the bats or stretches them to increase the area which they are to cover, the stripes will be obliterated or distorted-so as to immediately disclose the fraud.

It is to be noted that the marked glass wool belt forms a means of identification or a trademark appearing on-all' materials regardless of whether it is to be cut into bats, bulk, strips or any other type of package. While the present invention has been illustrated and described in connection with specific embodiments thereof, it is to be understood that modifications and variations may be made without departing from the scope or spirit thereof. For example, any number of spray guns may be used.

I claim:

1. A package comprising bats of fibrous mag terial, said bats compressively packed together with major faces thereof in juxtaposition, said material being loosely matted together in a manner to permit cleavage of the package at planes other than those of the said major faces of the bat-s. said bats comprising relatively narrow marginal faces which form a face of the package, and color stripes extending along the juxtaposed faces of the bats to said face of the package, the coloring material forming said stripes penetrating a sufficient distance into the bats to which they are applied to provide indicating markings visible on said face of the package and providing means to facilitate 'the separation of the package into its individual bats.

2. A package comprising a plurality of substantially flat, rectangular bats, each consisting of a mass of fibers loosely matted together and forming a" loose, flufly mat having mass integrity whereby the mat will retain its shape without external support, while permitting it to be readily reshaped and distended in any direction by a pulling force applied thereto, said bats being packed together with major surfaces of the bats lying against major surfaces of adjoining bats and adhering thereto so as to form an integral package, the juxtaposed surfaces being substantially coextensive, and coloring material applied to said surfaces and forming stripes extending along the said surfaces to the margins thereof, said coloring material penetrating a short distance into the bats so as to be clearly visible on the face of the bat comprising said margins, said stripes providing indicating means to facilitate the saparation of the package into its individual bats and further to indicate the identity of 'the bats when the latter are installed side by side within an insulating space.
